- Welcome to WAM2layers! — WAM2layers documentation
Welcome to WAM2layers! Welcome to the documentation of the WAM2layers moisture tracking code WAM2layers can be used to determine where precipitation originally evaporated (backtracking), or where evaporated moisture eventually ends up (forward tracking)
- Using WAM2layers — WAM2layers documentation
Using WAM2layers Through the command line The primary way of running WAM2layers is through the command line, much like pip, conda, git, cdo, et cetera It looks like this:
- Quickstart — WAM2layers documentation
Quickstart To help you get started, we provide two example cases: a backward tracking case for an extreme precipitation event over the Eifel region in July 2021 a forward tracking case of tracking evaporation over the Volta region in Ghana for July and August 1998 ERA5 data for these regions periods are available on 4TU and example configuration files are shipped with the package This
- Installation — WAM2layers documentation
Install WAM2layers from source In principle, the previous steps are enough to start using WAM2Layers In our experience, however, it is often useful and insightful to obtain a copy of the source code and create an editable installation This will allow you to look at the source code to see what is going on inside the model
- Tracking — WAM2layers documentation
Tracking The core of WAM2layers are the tracking routines The model includes forward and backward tracking Forward tracking takes evaporation over the tagging region as input and generates tracked precipitation as output Backward tracking takes precipitation over the tagging region as input and generates tracked evaporation as output Time tracking, distance tracking, and moisture recycling
- Theory — WAM2layers documentation
In WAM2layers (and in most other moisture tracking mdodels) several settings are optional regarding resolutions in time and space We recommend to at least critically think about these settings in the light of your research question rather than just applying the default values from the config file
- Developer’s guide — WAM2layers documentation
Developer’s guide This section explains how you can modify WAM2layers For example, to use input data from other sources We encourage you to consider contributing your changes so others can also benefit from your work Therefore, the explanation of the inner workings of WAM2layers are prefaced with instructions on how to collaborate on GitHub
- Obtaining input data — WAM2layers documentation
In addition to the time-dependent forcing data, WAM2layers also needs a tagging region This is used to define the tagging region from where to track moisture The region can be described by a netCDF file, shapefile, or simple bounding box For more info see wam2layers config Config tagging_region Alternatively, on the respository some notebooks are available which tackle more advances tagging
- Pre-processing — WAM2layers documentation
Pre-processing During the pre-processing step we make sure to convert the raw data into something that the tracking script understands This typically involves accumulating the data into two layers, deriving moisture fluxes (which are typically not included in standard model output) from variables that are commonly available, and converting the data to the right units and a regular grid if
